Role of heredity and environment on determining intelligence
Answers
Answer:
Explanation:
The Influence of Heredity and Environment
Today, researchers generally agree that heredity and environment have an interactive influence on intelligence. Many researchers believe that there is a Reaction Range to IQ, which refers to the limits placed on IQ by heredity. Heredity places an upper and lower limit on the IQ that can be attained by a given person. The environment determines where within these limits the person’s IQ will lie.
Despite the prevailing view that both heredity and environment influence intelligence, researchers still have different opinions about how much each contributes and how they interact.

Heritability is a mathematical estimate that indicates how much of a trait’s variation in a population can be attributed to genes. Estimates of the heritability of intelligence vary, depending on the methods used. Most researchers believe that heritability of intelligence is between 60 percent and 80 percent.
